... has significantly increased. The inspection procedure aims mitigating the uncertainty related to the asset degradation state, enabling a better quantification of the actual damage, and, consequently, increases the accuracy of remaining life projections. Since the costs involved in offshore subsea...

... reduce the maximum longitudinal strain and thermal fatigue damage by more than 50% as compared to using sleepers alone as mitigation. Therefore, this design adds a new option to allow increases in the sleeper spacing and improved reliability of buckle initiation. pipeline subsea lateral buckle...

... Abstract Subsea pipeline design for escarpment crossings proves complicated and time-consuming, primarily attributable to the excessive plastic strains encountered at the overbend and the extraordinary fatigue damage over long spans, exacerbated by the steep seabed conditions. Due...

... Abstract Dropped objects from surface vessels and facilities pose a significant threat to subsea assets. DNV’s recommended practice is robust, however it over-estimates the likelihood of dropped object impacts on subsea equipment. This results in more costly subsea designs and potentially...

...). These models have recently attracted the attention of the industry. Here, we describe a new tool that improves the decision-making process ranking the different decommissioning options of O&G subsea assets. This model considers 37 attributes gathered into 6 criteria: Safety, Environment, Waste management...

... Abstract Residual curvature installation of subsea pipelines has become a popular method for lateral buckling management because of its low-cost implementation and high reliability. The method is foreseen to remain attractive due to the positive operational feedback made available to the public...

... Abstract Vibrations in Subsea Production Systems are well recognized as a concern in the subsea industry. To identify the severity of the vibrations and potential accumulated fatigue damage, subsea vibrations need to be measured with great accuracy. Currently, accurate detection and subsea...

... Abstract S-lay installation methodology is an industry accepted method for the installation of subsea rigid pipelines. Pipeline initiation is a major operation during the start of S-lay and its selection is dependent on various factors including project requirements, field layout and strength...

... Abstract The main objective of this paper is to present a fully quantitative methodology combining reliability, availability and maintainability (RAM) analysis and cost-benefit analysis (CBA) approaches to determine the optimum sparing strategy for subsea components considering reliability data...

... Subsea processing is a key aspect of ExxonMobil’s subsea technology qualification efforts. Consequently, the reliable delivery of high voltage power to subsea equipment offshore, such as multi-phase pumps, is essential. The base case involves power delivery up to 30 kV via copper cables embedded...

... Over the last 10 years Statoil has developed subsea remote hot tap technology. The first use of the remote hot tap technology was the Tampen Link hot tap in 2008. The hot tap cutting operation itself was performed without the use of divers; however, the preparatory works including hyperbaric...

... 01 11 2011 Vibration is an important cause of fatigue damage in subsea piping systems (jumpers, rigid spools, tree pipework etc.). Presently, guidelines are available for a qualitative and quantitative vibration assessment for process pipework, but these are more applicable to topside...
